The MAX14611 is a quad bidirectional logic-level translator that provides the level shifting necessary to allow data transfer in a multivoltage system. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. A low-voltage logic signal present on the VL side of the device appears as a high-voltage logic signal on the VCC side of the device, and vice-versa.

The device is ideal for I²C bus as well as MDIO bus applications where open-drain operation is often required. The device features a three-state output mode (active-low TS). Drive active-low TS high to connect the pullup to the powered I/O port. This allows for continuous, undisrupted I²C operation on the powered side of the device while the level translation function is off. The MAX14611 is a pin-to-pin compatible upgrade to the MAX3378E in the TDFN package.

The MAX14611 features enhanced high-electrostatic-discharge (ESD) protection on all I/OVCC_ ports up to ±6kV HBM. The device operates over the -40°C to +85°C extended temperature range and is available in 3mm x 3mm, 14-pin TDFN and 4.9mm x 5.1mm, 14-pin TSSOP packages.

Product Detail

The MAX14611 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the functionality of the MAX14611 quad bidirectional low-voltage logic-level translator in a 14-pin TDFN package. The highly configurable PCB enables direct evaluation of the IC through multiple jumper-selectable methods. Input power to the EV kit is provided by a Micro-USB, type-B connector, or by an external 5V power supply. On-board LDO regulators provide the appropriate voltage for each component, and potentiometers allow the user to independently adjust the power supply for either side of the level translator.

Applications

  • Low-Voltage ASIC Level Translation
  • Mobile Phones
  • Portable Electronics
  • POS Systems
  • SPI, I²C, and MDIO Level Translation
  • Telecommunications Equipment
